Acute naphthalene poisoning following the non-accidental ingestion of mothballs
1Department of Emergency Medicine, Changi General Hospital, 2 Simei Street 3, Singapore.
Abstract:
Ingestional naphthalene mothball poisoning leading to prolonged haemolysis and methaemoglobinaemia can present with diagnostic and therapeutic challenges. A 19-year-old woman ingested 12 mothballs, and presented two days later with haemolysis and methaemoglobinaemia. She was treated with red blood cell transfusions, intravenous methylene blue, N-acetylcysteine and ascorbic acid. Continuous venovenous haemofiltration was conducted for 45 hours. Haemolysis with anaemia and methaemoglobinaemia persisted even after five days post-ingestion. Clinical and biochemical parameters improved. We describe a case of ingestional naphthalene poisoning with a good outcome after treatment.

Toxic Reactions: Overview
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...
